arm64: dts: qcom: msm8916-wingtech-wt88047: Add sound and modem

Browse Source 
Enable sound and modem for the Xiaomi Redmi 2. The setup
is similar to most MSM8916 devices, i.e.:

 - QDSP6 audio
 - Earpiece/headphones/microphones via digital/analog codec in
   MSM8916/PM8916
 - Audio jack detection via analog codec in PM8916
 - WWAN Internet via BAM-DMUX

except:

 - Speaker amplifier is connected to HPH_R (headphones) output of the
   analog codec. There is a separate analog switch that allows disabling
   playback via the headphone jack.
